RIM-LUG SHIM.

Specification of Letters Patent. Patented Aug. 15, 1922.

Application filed. January 26, 1820. Serial No. 354,159.

To aZZ 112720772 it may concern.

Be it known that I, Jnssn TEMPLE CURTIS, a citizen of the United States, residing at Bement, in the county of Piatt and State of Illinois. have invented a new and useful Rim-Lug Shim, of which the following is a specification.

This invent-ion relates to lug shims, and it is the primary object of the invention to provide a shim which may be readily and easilv applied to the ordinary securing lug employed in connection with demountable rims or the like, for preventing wear between the lug and the rim, and at the same time eliminating noise caused by the lug contacting with the rim associated therewitl A further object of the invention is to provide a shim which is adapted for use on lugs of various sizes and one which may be temporarily secured to the lug to prevent displacement, of the shim wit-h relation to the lug, in the event that the lug is removed.

it still further object of the invention is to :ovide a device of this character which will have connection with the lug in a man ner to prevent lateral movement of the shim with relation to the lug, thus insuring a proper positioning of the shim, at all times.

lVith the foregoing and other objects in view which. will appear as the description proceeds, the invention resides in the con1bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 illustrates a perspective view of a shim constructed in accordance with the present invention.

Figure 2 illustrates a shim as applied to a securing lug.

Figure 3 illustrates a fragmental sectional view of a felloe disclosing the lug as applied to the rim.

Figure 1 illustrates a. plan view of a blank of which the shim is formed, before the same has been bent to conform to the size and shape of a predetermined lug.

Referring to the drawing in detail, the reference character 5 designates the body of the shim which includes a strip of sheet metal having acut out portion 6 formed at one end thereof, and intermediate the side edges of the body 5, to provide the spaced arms 7.

The opposite end of the shim is provided with a tongue 8 formed intermediate the side edges of the body 5, and as shown, in operation this tongue 8 is curved transversely, so that the same will conform to the curvature of the bolt employed in connection with the lug for securing the lug to the wheel to which the same is to be applied.

As shown, by Figure 1 of the drawing,

the body 5 is positioned over a lug and bent intermediate its length as at 9, the upper portion of the shim being curved as at 10 so that the shim will conform to the upper curved surface of the usual lug, now in use, the arms 7 being now turned down over the flat surface 11 of the lug.

In operation, a lug provided with a shim constructed in accordance with the presentinvention, is provided between the felloe 12, and demountable rim 13, the securing nut 14-. of the bolt 15 being now screwed home to cause the lug to be wedged between the felloe and demountable rim 13.

From the foregoing it is obvious that due to the tongue 8 extending into the opening 16, formed in the lug l1, lateral movement of the shim with relation to the lug is absolutely prevented, and since the arms 7 closely engage the outer surface of the lug, the shim is firmly united with the lug to prevent displacement of the shim, in the event that the lugs are removed for the purpose of demounting or mounting a rim.

Having thus described the invention, what I claim as new is 1. In a lug shim, a body portion bent intermediate its ends to provide opposed sections, one of said sections having a pair of spaced arms adapted to be positioned over a lug, a tongue formed on one edge of the opposed section, said ton ue adapted to fit within the bolt opening of a lug.

2. In a lug shim, a body portion bent intermediate its ends to provide opposed sections, one of said sections having a cut out portion formed in its end to provide spaced arms, a tongue formed integral with the opposite section, said tongue adapted to fit within the bolt opening of a lug.

:1 lug shim e body portion bent in the curvature of said tongue adapted to 10 'jeiniefliiate its ends, to provide opposed seeconform to the curvature of the opening.
